*You may change your sexuality at will.
*You may change your gender at will. (Male, female, or futa if you want but you work out how that works exactly)
*Your body is changed into your ideal sexyness for when you're either gender.
*You operate under porn logic. (Things like instant thoroughly clean and lube assholes before anal sex, taking 20 inch dicks with no problem and shit like that.)
*You're always clean as if you just got out of a shower and B.O is eliminated with the mess slides right off you. (Individual parts may be toggled off, like for example you want some mess to stay on you. Also this works internally so you no longer need to brush your teeth or worry about bad breath.)
*Any hole you penetrate or are penetrated in always act as it's the perfect fit to give you maximum pleasure and no pain.
*STDs don't exist(Porn logic covers this, but thought I'd double down.)
*You and your partners you're having sex with no longer have a refractory and can keep going and going and going in you want to or you get unconscious from pleasure overlord or something. *shrugs*
*If you happen to be able to travel worlds, you can toggle porn logic to work for everyone in the entire world. You know what that leads to. You can also decide the intensity of said porn logic, like pick something between it only working in the bedroom and sex or constant city wide orgy sex zombies. (Also works if you can't travel worlds)
*You always have knowledge how to create the best sex toys, and sexual enhancers in any technology level. So if you for example can go to different worlds, this scales with their technology level, even works if they use magitech too.
*You always know how to create the maximum pleasure for any sexual encounter you have for both parties or just yourself if you don't care for the other person.
*You can edge someone perfectly without worrying about them accidentally having an orgasm without your say so if you're into this.
*You control your own fertility.
*Your enjoyment of sex will never decrease.
*You can summon basic sex toys- ropes, handcuffs, dildos, gags, candles, clamps, clothespins, etc - that only exist as long as they are being used for sex. Meaning they disappear right after sex. No mess no fuss.
*You gain a presence that draws people who want to fuck you or you want to fuck to you(Can be explained away as ridiculous charisma, pheromones, ect) that you control the intensity of by will. Either turning it off to "oh god why does the entire city want to rape you".
